An internal reticulated foam filter for a water filtration tank is an apparatus that thoroughly filters water of a variety of water filtration tanks. The apparatus includes a flow-management assembly, at least one inner tube, at least one outer tube, and a plurality of foam filters. The flow-management assembly positions the apparatus around a distributing tube of a water filtration tank. The at least one inner tube upholds the plurality of foam filters against a central tube of the distributing tube. The at least one outer tube releases the water filtered by the plurality of foam filters back into the water filtration tank. The flow-management assembly also includes a first cap, a second cap, a plurality of main inlets, a plurality of channels, and a plurality of main outlets. The plurality of main inlets is in fluid communication with the plurality of main outlets through the plurality of channels.

A durable and collapsible strainer basket for pool equipment includes a rigid annular top portion having a radially extending rim; and a flexible basket extending downward from the rigid annular top portion, the rim of the rigid annular top portion including a downward facing surface that extends radially outward beyond the flexible basket and that is positioned to rest on a ledge of a pool equipment cavity, wherein the flexible basket includes a tapered outer shape formed by two or more flexible silicone annular sections having a plurality of holes passing therethrough, wherein the two or more flexible silicone annular sections are configured to be collapsible such that the flexible basket includes a collapsed configuration and an expanded configuration.

An apparatus restricts access to an above-ground conduit outlet extending from an exterior wall of a building. The access restricting apparatus comprises a pipe cap defining a fluid passage open at both a proximal end and a distal end. The proximal end of the pipe cap is adapted to be connected in fluid communication with the conduit outlet. A screen is disposed across the opening at the distal end of the pipe cap for enclosing the interior fluid passage of the pipe cap within an enclosed space defined at least partially by the screen. Apertures in the screen restrict access to the conduit outlet of items larger than the apertures.

A cross-flow filtration device includes: a filter module which includes an inner chamber and an outer chamber separated by a semipermeable membrane; a process liquid tank which is configured to accommodate a process liquid; a pump which is configured to cause the process liquid to circulate to the inner chamber in the filter module and the process liquid tank; a replenisher tank which is configured to accommodate a replenisher liquid to be replenished into the process liquid tank, at least one or more sensors which are configured to measure a pressure of the circulating process liquid; and a replenisher measurement unit which is configured to measure an amount of the replenisher liquid supplied from the replenisher tank to the process liquid tank. The process liquid tank is configured to be continuously replenished with the replenisher liquid.

A durable and configurable strainer basket for pool equipment includes: a first rigid annular member having an outer surface sized to fit within a first pool equipment cavity having a first diameter; a second rigid annular member removably coupleable to the first rigid annular member, the second rigid annular member having an outer surface sized to fit within a second pool equipment cavity having a second diameter larger than the first diameter, but not to fit within the first pool equipment cavity having the first diameter; and a flexible silicone basket attached to the first rigid annular member.

Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.

A filter assembly includes a housing with an inlet and an outlet. The filter assembly also includes a tubular filter element located downstream of the inlet and upstream of the outlet and a sleeve element surrounding and blocking at least a portion of the filter element.
